The convenient thing about earnings season is that companies sometimes offer economic analysis along with their news. Caterpillar, for one, accompanied its new revenue and growth forecast with word that it expects weakness in the euro zone to persist into 2013.
Kathy Lien, a managing director at BK Asset Management, thinks the company may well be right.
"Caterpillar is saying out loud what many other companies are thinking," she told CNBC in an interview Monday. They are guardedly optimistic about the outlook for the U.S. and China, "but Europe remains a hotbed of uncertainty," Lien added.
The problem, Lien says, is Spain, which has so far declined to ask for a bailout despite clear economic distress. "The market won't accept anything short of a Spanish bailout," so conditions are tense, she said. (Read more: Will Spain Finally Give Markets What They Want?)
"All the other players are lined up" to provide aid, Lien said, but "between now and then we're still in freeze mode."
In Britain, however, an upcoming growth report could send the pound higher, Lien says.
So Lien wants to sell the euro against thepound, ntering the trade at 0.8100 with a stop at 0.8175 and a target of 0.7975.
